Moving an Exchange 2007 Server to Another DomainIt is not supported to move an Exchange 2007 server from one domain to another domain. Additionally, it is not supported to run the setup /mode:recoverserver command against an Exchange computer object that previously existed in a different domain. If you must move an Exchange 2007 server to another domain, you must instead perform one of the following tasks:
- If you want to move an Exchange server between domains within the same forest in a planned scenario (for example, due to a reorganization), we recommend that you install new servers in the new domain. You can then move the mailboxes from the server in the old domain to the server in the new domain. You can also replicate public folder content to the new server. For more information about how to move mailboxes in Exchange 2007, see How to Move a Mailbox Within a Single Forest. For more information about replicating public folder content, see Managing Public Folder Replication.
- If you want to move an Exchange server between domains due to an unplanned failure or disaster, we recommend that you restore the Exchange 2007 databases and mailboxes to a new Exchange server that you install in the new domain. To move the current Exchange information to the new Exchange server, you must have a good backup copy of the databases that were on the failed server. For more information about restoring a database to a new server, see How to Restore a Mailbox Database to a New Server with Database Portability.
